STOVE OR RANGE.

Specification of Letters Patent.

Patented April 6, 1909.

Application filed. June 30, 1908. Serial No. 441,238.

To all whom it may concern:

Be it known that I, DANIEL D. BERRY, a l citizen of the United States,and resident of Springfield, lvfissouri, have invented certain new anduseful Improvements in Stoves or Ranges, of which the following is aspecification.

This invention relates to improvements in stoves or ranges and consistsin the novel arrangement, construction and combination of parts as willbe fully hereinafter described and claimed.

The object of my invention is to construct a stove or range having anair circulating passage located beneath and to one side around a portionof the oven walls and bottom 1n winch are located bridge walls andFigure 1 is a perspective view of my invention showing the front wallremove-d. Fig. 2 1s a cross sectional view taken on the line 22 ofFig. 1. Fig. 3 is an enlarged detail sectional view of a portion of thewalls forming the air passage showing the bridge wall and partition.

.In the construction of my invention, I provide an ordinary stove orrange consisting of the end walls 1-, front wall 5 and rear Wall 6, top7 and a bottom 8. In the casing is located the ordinary oven 9 andbeneath the same and suitably located is the warm oven 10. The top 11 ofthe oven is arranged to project beyond the end wall 12 of the oven andto the projection is secured the wall 13 which forms between said walland the oven end wall 12, an air passage 14. In this passage and betweensaid walls is located a horizontal partition 15 extending from frontwall 5 to back wall 6 approximately on a level with the bottom 16 of theoven, and in the oven wall 12 are formed a plurality of openings 17located a short distance above the bottom 16 through which the heatedair from the interior of the oven enters into the passage 14. Beneaththe bottom 16, I provide a second bottom 18, the right hand end thereofbeing bent upwardly and secured 'to the right hand end wall 30 of theoven, the opposite end of the bottom 18 being a continuation of the endwall 13, the corner being sufficiently rounded as indicated by thenumeral 19. The right hand end of the bottom 18 being secured to thewall 30 at a height sufficient to form a circulating passage 20 so as topermit the air to enter into the lower right hand corner of the oventhrough the perforations or air inlets 21. The location of the bottomsl6 and 18 form an air passage 22 through which the air is permitted tocirculate and enter into the oven at the lower right hand corner aspreviously described. In the passage 22, I locate bridge or deflectingwalls 23 which extend from the front and rear walls diagonally towardthe end wall 12 of the oven forming an elongated air inlet 24, betweenthe inner ends of the bridge or deflecting walls; the said wallsdividing the air passage 22 forming a fresh air inlet chamber 25 intowhich the fresh air is admitted through the openings 26 formed in thefront and rear walls of the casing and the said fresh air as it entersinto the chamber 25 from the exterior is gradually heated and permittedto enter into the cham ber 22 through the inlet 24 and enter into theoven through the openings 2]. This heated air is then permitted to passout of the oven by way of the openings 17 in the wall 12 an d enter intothe passage 14 located at the end of the oven wall and pass out into thecombustion chamber 27 through the openings 28 formed in the wall 13. Thefuel is placed in the fire-box 29 which is of ordinary construction therounded corner 19 of the bottom 18 projecting over the fire-boxpermitting the heat to contact with the same and heat the fresh air asit is admitted through the openings 26. The direction and circulation ofthe air are shown by the arrows in the drawing.

By this arrangement the current of air after entering the inlets 26travels first diagonally across the left hand corners of the oven,thence to the right under the oven, thence through the openings 21 intothe interior of the oven, thence out of the oven through the openings 17into the passage 1 1 and out through the openings 28 into the combustionor smoke flue 27, mingling with the particles of combustion andassisting in burning the same.

This invention is an improvement over my former patents issued, July 7,1903, No. 733,129; May 30, 1905, No. 791,400 and also a pendingapplication filed Jan. 22, 1908, Serial No. 412,067 and allowed April 4,1908.

Having fully described my invention what I claim is:

1. A stove or range comprising an outer casing; an oven; an additionalend wall and bottom located to one side and beneath the oven forming anair passage; a division wall located between the end walls; diagonalbridge or deflecting walls located between lit) the bottoms dividing theair passage into two chambers and forming an inlet through which i theair is permitted to pass from one chamher to the other, all of the endwalls being 1 provided with openings through which the air is permittedto circulate; the front and l rear walls of the casing provided withopenings for the admission of the fresh air from 1 the exterior into thechamber in front of the bridge walls, substantially as specified. i 2. Adevice of the class described comprising a casing; an oven located inthe casing; an end wall located parallel with the end wall of the oven;a bottom located beneath.

; the oven bottom and forming a continuation of the end wall; the righthand end of said bottom being bent upwardly and secured to the righthand end of the oven; said end l walls and bottoms forming an airassage; l a horizontal partition wall located etween 5 the end walls andapproximately on a parall lel line with the oven bottom; said end wallsl being provided with openings through which 1 the air circulates;bridge walls located in the air passage between the bottoms and locateddiagonally oven wall forming an air inlet between the inner ends of saidbridge walls; the front and rear walls of the casing provided withopenings for permitting the air air passage in front of the bridgewalls; the right hand end of the oven wall provided with openings topermit the air to enter into the oven from the air passage beneath; thesaid openings so arranged as to permit the air to pass through the ovenand out into the combustion chamber or smoke flue assisting in theburning of the articles of combustion, substantially as specified. Intestimony whereof, I have signed my name to this specification, inpresence of two subscribing witnesses.
